昨晚看到一篇爬取百度地图信息的的代码，我更改了城市，关键词，页码等，完成了获取有关“筛网”店铺的信息。

代码如下：

import requests

import re

import csv

import time

def BusinessFromBaiduDitu(citycode = '287',key_word='筛网',pageno=0):

parameter = {

"newmap": "1",

"reqflag": "pcmap",

"biz": "1",

"from": "webmap",

"da_par": "direct",

"pcevaname": "pc4.1",

"qt": "con",

"c": citycode,        # 城市代码

"wd": key_word,       # 搜索关键词

"wd2": "",

"pn": pageno,         # 页数

"nn": pageno * 10,

"db": "0",

"sug": "0",

"addr": "0",

"da_src": "pcmappg.poi.page",

"on_gel": "1",

"src": "7",

"gr": "3",

"l": "12",

"tn": "B_NORMAL_MAP",        # "u_loc": "12621219.536556,2630747.285024",

"ie": "utf-8",        # "b": "(11845157.18,3047692.2;11922085.18,3073932.2)",  #这个应该是地理位置坐标，可以忽略

"t": "1468896652886"}

headers = {    'User-Agent': 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_12_3) AppleWebKit/537.36(KHTML, like Gecko) Chrome/56.0.2924.87Safari/537.36'}

url = 'http://map.baidu.com/'

htm = requests.get(url, params=parameter, headers=headers)

htm = htm.text.encode('latin-1').decode('unicode_escape')  # 转码

pattern = r'(?<=\baddress_norm":"\[).+?(?="ty":)'

htm = re.findall(pattern, htm)  # 按段落匹配

for r in htm:

pattern = r'(?<=\b"\},"name":").+?(?=")'

name = re.findall(pattern, r)        #if not name:

pattern = r'(?<=\b,"name":").+?(?=")'

name = re.findall(pattern, r)        #print(name[0])  # 名称

pattern = r'.+?(?=")'

adr = re.findall(pattern, r)

pattern = r'\(.+?\['

address = re.sub(pattern, ' ', adr[0])

pattern = r'\(.+?\]'

address = re.sub(pattern, ' ', address)        #print(address)  # 地址

pattern = r'(?<="phone":").+?(?=")'

phone = re.findall(pattern, r)

try:

if phone[0] and '",' != phone[0]:

phone_list = phone[0].split(sep=',')

for number in phone_list:

if re.match('1', number):

print(citycode+name[0]+','+address+','+number)

writer.writerow((name[0], address, number))

except:

continue

print(citycode + '  ' + key_word + '  ' + str(pageno))

现在开始写我搜“丝网”“筛网”(key_word)的代码获取想要的数据，也要改城市代码(citycode)城市代码文件链接

#citynumlist是百度地图城市代码列表

citynumlist = ['33','34','35'

'''''''''''''''''

'370','371','372']

keywordlist = ['丝网','筛网']

start = time.time()

num = 1

#建立csv文件，保存数据

csvFile = open(r'/Users/apple888/PycharmProjects/百度地图/Data/%s.csv' % 'CityData','a+', newline='', encoding='utf-8')

writer = csv.writer(csvFile)

writer.writerow(('name', 'address', 'number'))

for citycode in citynumlist:

for kw in keywordlist:

for page in range(10):

BusinessFromBaiduDitu(citycode=citycode, key_word=kw, pageno=page)

#防止访问频率太高，避免被百度公司封

time.sleep(1)

if num%20 == 0:

time.sleep(2)

if num%100== 0:

time.sleep(3)

if num%200==0:

time.sleep(7)

num = num + 1

end = time.time()

lasttime = int((end-start))

print('耗时'+str(lasttime)+'s')

程序运行了大约三个小时，抓取了1085条有用信息信息
